Was driving and the air conditioner quit blowing cold. Then the temperature gauge went to hot. Then the check engine light went on and the car would accelerate but didn't want to accelerate. Ideas? Thoughts?

SOURCE: The heater is blowing cold but the engine temperature reads high

Hi
I would first check to see if both heater hoses are hot to the heater.
if 1 is hot and 1 is cold the heater control valve is closed or the heater core is plugged.

Sounds like your temperature actuator is not moving or your temp door is broken. On max a-c ,coolant is shut off to your heater core allowing only cold air in.

SOURCE: heater is blowing but its cold air not hot air 2000 expedition

Make sure the heater core is in the open position by using the shut off valve and turning it to open. next, you may have a malfunction in the direction door the directs the air flow in the dash. a lever may have become lose or separated. may be a bad servo motor not directing the door to move to the heater position. i would start by checking that shut off valve first on the heater core.

simply "adding a can"is a good way to end up with non-functional A/C. the typical system has high/low pressure switches that enable/disable the system. you need to be at the correct volume of refrigerant as specified on the sticker under the hood. i recommend using the proper equipment, evacuating, pulling a vacuum, and then refilling the system with the appropriate amount.

My 2002 Expedition air conditioner will sometimes blow hot air and others cold air


I would check the following possibilities:
1. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. Start engine and set to max ac. When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. If not, the compressor is not engaged. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). If it is not engaged, then your compressor clutch is probably going out. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. If clutch is bad, compressor would need to be replaced (sold as one unit). This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.

2. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.

Could be other issues, but I would start with these.

Good luck

Rear A/C blows hot air instead of cold on a 2002 ford expedition


The most common part that fails is the temperature actuator. It is located on the right rear of the suv. The trim panel has to be accessed to replace the actuator.

When i turn on the heat it does not blow hot. it is cold then it warms up a little but barely? what do i need to do so it will blow out hot air and not cool or "room temperature"?


First thing is to check the gauge to make sure that the engine is coming up to operating temperature. If it is not you might need a thermostat, but first check to make sure that the coolant level is full this will make the cabin heating system perform poorly, if those both check out then you either don't have water circulating (water pump) or the heater core is bad and will need to be replaced. If the heater core and water pump are both good then the problem lies within the heating controls or ducting. The dash control may be faulty and not closing the blend door to shut out the cold air or the blend door may be blocked by something foreign in the system or the blend door itself may be faulty.
